The nuclear decay database in fission product mass region

Abstract

ccurate and reliable nuclear decay database is essential for fundamental and applied nuclear relative researches. However, the decay data is not as accurate as usual impression and still need improvement. Hence, the new Chinese nuclear decay database in fission product mass region (A=66-172) has been developed under the joint efforts of CNDC working group, based on several major national evaluated data libraries. Totally 2358 nuclides have been included in this decay database. Two main data formats, ENSDF and ENDF, are adopted. For the total mean  and  energies, data from total absorption gamma ray spectroscopy measurement are adopted when available. For some nuclides without experimental measurements, theoretically calculated values were added.
